Not able to connect to TV using chromecast

Question

I've been trying to implement chromecast to my android app. Even after following the documentation i am not able to establish a connection.

SessionManagerListener<CastSession> mSessionManagerListener = new SessionManagerListener<CastSession>() {
 @Override
 public void onSessionStarting(CastSession castSession) {
      for (ChromeCastSubscriber castListener : getSubscribers()) {
           castListener.onCastConnecting();
           }
       }
    
 @Override
 public void onSessionStartFailed(CastSession castSession, int i) {
    // Failed
 }
};

It starts the connection and goes to Failed method. I am not able to establish a connection here, Any Help? I am on same network on both, Tv and Mobile.

I am getting Error code as "2472" which is not mentioned in the Error code list https://developers.google.com/android/reference/com/google/android/gms/cast/CastStatusCodes

Kindly guide me ahead.
